Adventure Time
The story of the popular CartoonNetwork show Adventure Time, the lives of everyone such as the Ice King. To my understanding it seems that everything started with him because of his finding of the ice crown. When the ice king made his video journals he was engaged to what it seems like princess bubblegum or the queen of the candy kingdom. When he found the ice crown he began to create problems for the whole land of Ooo but when the soon to be ice king found the crown he began to change the environment around him causing him to slowly and progressively lose his memory to the ice crown. Raging the great war people soon began to get upset with the ice king's powers beginning slowly to conjure new types and studies of ancient artifacts and new magics. All leaving the old city in which where all humans lived became the place of where Susan Strong lives with all the mutated non humans. Which I have lead to the conclusion of Susan Strong being Finn's mom having seen that she did not her son to become a cave dweller like herself. Leaving Jake's family to find him wrapped in a leaf crying which around that time the war raged including the dog and unicorn war. But I am getting off topic from the Ice King, now as I have already said Ice King was engaged to the queen of the candy kingdom meaning his love for wanting a wife and capturing princess bubblegum because she reminds him of the queen. In all this chaos an important person has been forgotten having no one. Marceline has been through this war as a little child while crossing paths with the Ice King recording everything he did until he completely lost his memory. The ice king took a picture of Marceline when she was a little girl which was the same age Finn and Jake went to go retrieve that memory that Ash wanted erased. Now I may be jumping to a rash conclusion such as the Ice King was engaged to the queen of the candy kingdom and is seen that Marceline could possibly be a experiment to create a friend for princess bubblegum.
